MILLARD F. GEORGE, OF CHELSEA, VERMONT.

CATTLE-STANCHION.

Application filed March 29, 1909.

To all whom it may concern:

Be it known that I, MILLARD F. GEORGE, of Chelsea, in the county of Orange and State of Vermont, have invented certain new and useful Improvements in Cattle-Stanchions, of which the following is a specification.

This invention relates to a cattle stanchion which comprises head and foot blocks adapted to swing on vertical pivots in alinement with each other, and stiles forming the confining sides of the stanchion, one of the stiles being attached rigidly to the head and foot blocks, while the other stile is hinged to the foot block and adapted to swing toward and from the opposite stile to open and close the stanchion.

The invention has for its object to provide a stanchion of this character in which the closing movement of the swinging stile shall be effected by the entrance of the animals head and a portion of the body between the two stiles, the swinging stile being automatically moved to its closed position, so that a cow entering the stanchion will lock herself therein.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side view of a stanchion embodying my invention, the stanchion being open. Fig. 2 represents a view similar to Fig. 1, showing the stanchion closed. Fig. 3 represents a perspective'view of the upper portion of the stanchion body adjusted as shown in Fig. 1. Fig. 4 represents a section on line 4-4 of Fig. 2. Fig. 5 represents a section on line 55 of Fig. 1. Fig. 6 represents an end view of the entire stanchion in the adjustment shown in Fig. 1. Fig. 7 represents a view similar to Fig. 6, showing the stanchion in the adjustment represented by Fig. 2. Fig. 8 represents a section on line 88 of Fig. 1. Fig. 9 represents a view similar to a portion of Fig. 1, showing the adjustable stop hereinafter referred to in its operative position. Fig. 10 represents a top view of the portion shown in Fig. 9.

The same reference characters indicate the same parts in all the figures.

In the drawings, 12 represents a fixed art of the stanchion, which 1 term a head p ate,

the same being preferably composed of wood adapted to be bolted or otherwise attached to an overhead support in a stable or tie-up.

The movable portion of the stanchion, which I term the stanchion body, is composed of a head block 13 connected by a pivot bolt 14 with the head plate 12, a foot block 15 connected by a pivot bolt 16 with a supporting base such as a stable floor, the latter having a socket to receive the bolt, a body stile 17 rigidly attached at its ends to the head and foot blocks, and a swinging stile 18, the lower end of which is pivoted or hinged at 19 to the foot block, the swinging stile being movable toward and from the body stile, and adapted to occupy an open position, as shown in Figs. 1, 3, and 6, and a closed position, as shown in Figs. 2 and 7.

Means are provided for automatically moving the swinging stile to its closed position, said means as here shown, comprising a spring 20 connected at one end with the body stile 17, and a flexible cord 21, or other connection, attached to the other end of the spring, and passing through an orifice in the body stile, one end of the said connection being attached at 22 to the swinging stile. When the swinging stile is in its open position, the spring is extended and acts to move the swinging stile to its closed position, when the latter is released from engagement with the locking means, hereinafter described.

23 re resents a locking member which is preferably a wooden bar loosely connected. with the head block 13 by a two-armed shackle 24, preferably formed as shown in Figs. 1, 2, and 3, the shackle being loosely pivoted at one end to the head block and at the other end to the locking member. In the under side of the locking member is formed a notch 25 which is adapted to engage the upper end of the swinging stile 18, the inner end of the locking member at the same time engaging one side of the head block 13, and resting on a shoulder 27 formed thereon. The locking member in this position acts as a strut to hold the swinging stile in its open position against the stress of the spring 20.

'28 re resents a fixed detent attached to the head pl ate 12, said detent being a short stud projecting downwardly from the head plate and adapted to bear on the upper side of the locking member 23, and hold the inner end of the stanchion body, and will therefore impart a partial rotation to the stanchion body in the direction indicated by the arrows yy. This movement of the stanchion body will remove the locking member 23 from under the detent 28, thus releasing the locking member, and permitting the spring 20 to move the swinging stile to its closed position, the loose connection between the ocking member and the head block afforded by the shackle 2 1 permitting the inner end of the locking member to swing upwardly under the pressure exerted on it by the spring until the notch 25 of the locking member is disengaged from the upper end of the swinging stile, the latter swinging under the locking member, which finally drops against the outer side of the swinging stile, as shown in Fig. 2, thus confining the swing ing stile in its closed position.

It will be seen from the foregoing that the stanchion body is automatically closed by the animal entering it, so that the animal can be properly said to lock herself in, the space between the stiles when the stanchion body is closed, being so narrow as to prevent the withdrawal of the animals head from between the stiles.

29 represents a fixed back stop rigidly attached to the head plate 12, and projecting downwardly therefrom in osition to bear upon the back side of the loc ing member 23, when the stanchion body is open and adjusted as shown in Figs. 1 and 6, said stop being preferably a bent metal rod formed and secured to the head plate as indicated in Fig. 8. The back stop 29 enables the stan chion body to be adjusted to the predetermined position shown in Fig. 6, this being the position required to cause the detent 28 to engage the locking member 23. The movement of the stanchion body caused by the contact of the animal with the body stile 17, moves the locking member 23 away from the back stop 29.

The upper end of the swinging stile 18 is provided with an upwardly projecting metal tenon 30 adapted to enter a groove 3] formed in the under side of the locking member 23, thus preventing relative displacement of the locking member and the swinging stile when the latter is locked in its open position. The upper end of the swinging stile is also provided with a laterally projecting tenon 32 which enters a groove 33 formed in one end of the head block 13 when the swinging stile is in its closed position, provision being thus made for preventing relative displacement of the swinging stile and the head block when the stanchion body is closed.

34 represents a swinging shackle which engages a notch 35 formed in the outer side of the swinging stile, said shackle constituting a stop which limits the outward swinging movement of the swinging stile when thelatter is locked in its open position.

36 represents a guide for the shackle 34, said guide being attached to the swinging stile and extending across the notch 35 to prevent the shackle 34 from swinging looselyaway from the stile 18.

37 represents an adjustable front stop which has a swinging connection with the head plate 12, and is adapted to be adjusted to bear on the outer side of the locking member 23, as shown in Figs. 9 and 10, when for any reason it is desired to prevent the stanchion body from being closed by contact of an animals body with the body stile 17.

'Normally, the adjustable stop 37 will be adjusted as indicated in Figs. '1, 2, 6, and 7, in which position it is inoperative.

I do not limit myself to the details of construction here shown and described, and the same may be variously modified without departing from the spirit of my invention.

Duplicates of the detent 28, and stops 29 and 37 are preferably provided, as shown in Figs. 1, 2, 6, and 7, to enable the position of the stanchion body to be changed to locate the swinging stile at the right hand side instead of at the left hand side, as here shown.

I claim:
